Patented Nov. 16, 1909.

Application filed August 17, 1908. Serial No. 448,890.

To all 'whom it may concern:

Be it known that I, JOHN C. HARING, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new anduseful Im rovements in Polypoint Pencils, of which t e followin is a specification.

This invention re ates to polypoint pencils, and its object is to provide a pencil having a plurality of leads of diderent colors or degrees of hardness with means for bringinanydesired lead into position for use.

o this end the invention consists in certain `novel means by which a single` operating mechanism can be caused to act upon any selected lead carrier, as hereinafter set forth and particularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a longitudinal sectional elevation of a pencil embodying my invention, the parts being shown exaggerated in size for the sake of clearness. Fig. 1a is a longitudinal section showing the pencil extended ready for use. Fig. 2 is a cross section on the line 2-2, Fig. 1. Fig. 3 is a sectional elevation of the group of guide tubes, carriers and collars constituting the rotatable magazine. Fig. 4 is a perspective view of the driving sleeve. Fig. 5 is an end view of the same. Fig. 6 is a perspective view of the cam. Fig. 7 is a perspective view of the lower collar on the magazine, with its ribbed spring lingers. Fig. v8 is a sectional elevation of a modification. Fig. 9 is a sectional' elevation of the magazine in said pencil. Fig. 10 is a cross section of said magazine. Fig. 11 is an elevation of a guide tube and carrier. Fig. 12 is an elevation of the complete pencil, closed. Fig. 13 shows the notched collar at the upper end of the magazine, and Fig. 14 shows the upper end of the propelling sleeve.

In the pencils illustrated in the drawing, there are three lead-carriers, but it will be readily understood that any convenient number may be used. The three guide-tubes 1 are placed parallel with each other, in con tact, and equidistant from a common axis. They are preferably soldered together, and are also attached to encircling collars (numbered 2, 3, 4 in Sheet 1) so as to lforma magazine. Each guide-tube has a longitudinal slot 5 in its outer side, toreceive 'y from the lead-carrier 7 which is adapted to slide lengthwise in the guide-tube. When housed, the upper ends of the carriers roject above the upper ends of the guide-tu es. The word upper has reference to the position in which the parts are shown in t e drawings, and is used merely for convenience of description.

, Referring now especially to the pencil shown in Sheet 1 of the drawings the upper collar 2 has notches 8 registering with the slots 5 in the guide-tubes, so that the pins 6 can enter said notches. Said collar is also provided with one or more longitudinal ribs 9. 'I prefer to use three ribs spaced equidistant, and to ive them rounded surfaces, as shown. The 2tIower collar 4 is provided with three spring fingers 10, spaced equidistant, and each having a rounded longitudinal rib 11, in line with the ribs 9.` The collar 3 is located adjacent to the free ends of said spring lingers. Rotatably mounted on the magazine and abutting between the collars 2 and 3, is a sleeve 12 in which is cut a helical slot 13, of rather long pitch. The upper end of said slot is open, so that it can be engage with any one of the pins 6; the slot being cut away a little at 14 to facilitate the entrance of the pin. The rotation of this sleeve causes the pin to traverse the slot 5 in the guide-tube, thereby ejecting or housing the lead-carrier. For this reason, I shall refer to this sleeve. as the propelling sleeve. A

pin 15 projects from the propelling sleeve 1 and engages with a helical slot 16 cut in a non-rotatable driving sleeve 17 which encircles the propelling sleeve. When this driving sleeve is moved longitudinally it causes a rotation of the propelling sleeve by reason of the action of the helical slot 16 upon the pin 15. The driving sleeve 17 is secured to the inside of the pencil case or barrel 18, which extends above the upper endof the magazine and is closed by a head 19, the inner surface of which is provided with a cam 20, which stands close to the collar 2 when the pencil is closed; as shownA in Fig. 1. The lower end of the magazine projects below the lower end of the bari'el, and is inclosed in a sheath 21, to which it is secured. Said sheath preferably enters the barrel between the inner surface thereof and the lower portion of the driving sleeve 17. The cam 20 is adapted to bear upon the upper end of one of the carriers and push 'it downward until its pin 6 enters the cutaway portion 14 of the This brings t upon by said causes it to rotate. parts iii this positio spring fingers l0 are all longitudinal shall surface of the dri desired to bring anot line with the slot in the entire magazine the said sleeve, and turning it. yield and permit the r grooves until said with said fingers, outwardly into sa lock the parts in t By this rotation o rier is brought u downward so that 13. lfVhen th barrel to eject the spring ii grooves 22 in t the col tively lock the long as the penci be changed without housin moving the ribs 9 from shown in Fig. l.

A pencil providedy with a magazine 27 carries an index 29.!l comprising a plurality of lead-carriers, a bring the helical slot rotatable propelling sleeve encircling said on to engage the del magazine and having a helical propelling 130 sired carrier. A cap 3Q covers the upper ends of the carriers which project be ond the guide tubes. Said cap is capabe of longitudinal'movement in the section 27 of the jacket, being limited in its range of movement by flanges 3l or otherwise. In operation, the section 27 is rotated until its index 29 points to the desired mark 28, thereby bringing the upper end of the helical slot 24 in line with one of the notches 8. 7 The cap 30 -is then pushed in, as shown in Fig. 8, forcing all the carriers downward; the pins 6 entering the slot 24 and the beveled notches 25. Upon rotating the section 27 and its attached propelling sleeve, the gf) carrier whose pin vhas entered the slot 24 will be ejected, while the beveled notches 25 will merely force the other two pins up into the" notches 8 so that they will not prevent the rotation of the propelling sleeve. g5 This action also restores the cap 30 to its normal position.

It will be observed that my invention thus enables one to have at his command a. plurality of different pencil points compactly ,Q0 housed in a case of moderate size, any desired point being capable of ejectment by means of a single mechanism.

Having thus described my invention, what I claim is:

1. A pencil provided with a magazine c om rising a plurality of lead-carriers, a I sing e'rotatable. propellingsleeve surrounding said magazine and normally out of en- 2. 'pencil provided with a magazine comprising aplurality of lead-carriers, a single propelling sleeve rotatable relatively 10.5

A pencil comprising a rotatab e group sleeve surrounding said group, and a cam slot, a non-rotatable longitudinally-movable driving sleeve surroundin said propelling sleeve and having a he ical slot, a pin on said propelling sleeve engaging with the slot in the driving sleeve, and a cam a1'- ranged to act on all of said carriers as the magazine is rotated, for forcing each carrier successively into engagement with the slot in the propellin sleeve.

6. A pencil provi ed with a plurality of lead-carriers grouped into a magazine, ribbed spring fingers on said magazine, a ribbed collar on said magazine, a non-rotatable longitudinally-movable driving sleeve l containing longitudinal grooves to cooperate with the ribbed collar and fingers, a propelling sleeve inside of said drivlng sleeve and adapted to be rotated thereb and means for causing any desired one o vsaid carriers to engage with said pro elling sleeve.
